BAR MAINTENANCE

If your saw cuts to one side, has to be forced

through the cut, or been run with an improper

amount of bar lubrication it may be neces-

sary to service your bar. A worn bar will dam-

age your chain and make cutting difficult.

After each use, ensure ON/STOP switch is

in the STOP position, then clean all sawdust

from the guide bar and sprocket hole.

To maintain guide bar:

S Move ON/STOP switch to the STOP posi-

tion.

S Loosen and remove chain brake nuts and

chain brake. Remove bar and chain from

saw.

S Clean the oil holes and bar groove after each

5 hours of operation.

S Burring of guide bar rails is a normal

process of rail wear. Remove these burrs

with a flat file.

S When rail top is uneven, use a flat file to re-

store square edges and sides.

Replace guide bar when the groove is worn,

the guide bar is bent or cracked, or when

excess heating or burring of the rails occurs.

If replacement is necessary, use only the guide

bar specified for your saw in the repair parts list

or on the decal located on the chain saw.

CHAIN SHARPENING

Chain sharpening is a complicated task that

requires special tools. We recommend that

you refer chain sharpening to a professional

chain sharpener.

CARBURETOR ADJUSTMENT

WARNING: Thechainwillbemoving

during most of this procedure. Wear your pro-

tective equipment and observe all safety pre-

cautions. The chain must not move at idle

speed.

The carburetor has been carefully set at the

factory. Adjustments m ay be necessary if

you notice any of the following conditions:

S Chain moves at idle. See IDLE SPEED--T

adjusting procedure.

S Saw will not idle. See IDLE SPEED--T ad-

justing procedure.

Idle Speed-- T

Allow engine to idle. If the chain moves, idle

is too fast. If the engine stalls, idle is too slow.

Adjust speed until engine runs without chain

movement (idle too fast) or stalling (idle too

slow). The idle speed screw is located in the

area above the primer bulb and is labeled T.

S Turn idle speed screw (T) clockwise to in-

crease engine speed.

S Turn idle speed screw (T) counterclock-

wise to decrease engine speed.
